1. One or more computer-readable storage media having computer-readable instructions thereon which, when executed by one or more processors, cause the one or more processors to perform a method comprising:

  • extracting high level structure information about a web page using markup language tag tree selection rules to define high level boundaries;

    extracting low level structure information within each high level structure information by;

    identifying explicit visual boundaries from the properties of one or more tags of the markup language tag tree by clustering the one or more tags in a pattern detection algorithm enabling the detection of one or more regions within the high level structure information;

    identifying visual units by boundary detection from the markup language tag tree corresponding to each high level structure information; and

    projecting each visual unit perpendicularly to an axis to identify implicit boundaries between the visual units;

    storing the high level boundaries, the implicit boundaries, and the extracted high and low level structure information of the web page using an annotation mechanism, andfor a predetermined display screen having a width, identifying a plurality of sub-pages of the web page using the high level boundaries, the implicit boundaries, and the extracted high and low level structure information of the web page, wherein each sub-page has a width not greater than the width of the predetermined display screen;

    forming a thumbnail image of the web page having partitions corresponding to the one or more sub-pages;

    forming a hyperlink to each sub-page from a corresponding partition of the thumbnail image of the web page; and
